X server crashes when starting Xv apps
About every other time that I start an application which uses Xv (bttv, xine, etc.), my X server crashes and dumps me back to the login prompt.
Athlon XP 1800+
Epox 8KHA+ (Via KT266A) motherboard
Inno3D GF4 Ti4400 (128MB)
I'm using the kernel AGPgart driver from 2.4.19 with the latest NVidia driver (compiled from source) and XFree 4.2.0.
Is anyone else experiencing similar problems? It seems weird that it doesn't always crash, but I can't spot anything different in the circumstances that lead to it...
